The Griffin Armament M4SD 3 Prong Flash Hider delivers a high-performance, Gen 3 design that interfaces seamlessly with GATE-LOK suppressors, including M4SDK variants and the QD Blast Shield, providing an advanced alternative to traditional A1/A2 Birdcage flash suppressors while significantly reducing flash signature and muzzle climb. This CNC machined, outside diameter ground 17-4PH stainless steel device wears a durable Black Nitride finish and is engineered for maximum durability, with precisely calculated porting to neutralize muzzle movement and an ambidextrous QD Mount for versatile mounting options. The 1/2x28 thread fits 5.56mm carbines, and the unit ships with a shim set and over-travel stop washer, plus it is predrilled for pinning and welding to a 14.5" barrel to achieve a 16" non-NFA length carbine. It features a .863" diameter, 2.25" overall length, and a light 2.4 oz weight, with an over-travel tab positioned at the 6 oclock orientation, ensuring consistent performance without ringing or pinging. The M4SD Gen 3 aims to minimize flash while maintaining reliability and enduring use in demanding field conditions, and it is proudly marked with the Griffin Laser Logo.
